MACHINE FOR COATING, COLORING, OR OTHERWISE T REATING PAPER.

Application filed April 28, 1924. Serial No. 709,076.

To all whom it may concern:

Be it known that I, EMIL Penn, a citizen of the United States, residingat Austin, in the county of Potter and State of Pennsylvania, haveinvented certain new and useful Improvements in Machines for Coating,Colorin or Otherwise Treating- Paper, of which t e following is aspecification.

My invention relates to machines for coating, coloring or otherwisetreating aper and similar material, and the particular object of myinvention is toprovide means, whereby various substances or colors canbe applied to the material treated in one operation. In the case ofcoloring paper, the colors may be so applied that at their line ofcontact they will to some extent mix so as to produce a composite coloror a rambow effect. For a full understanding of my invention, I refer tothe annexed drawing in which I have shown by way of illustration in abodiment of my invention, Fig. 1 being a side elevation of theapparatus, showing the relative position of the various parts enteringinto Fig. 2 is a plan view on an enlarged scale of the trough containingthe colors or other substances to be applled to the material to betreated; Fig. 3 is a sectional view of the trough to show the method offilling the same with various colors; Fig. 4 is a detail View showing acolor applying roll with a pad bearing against the same.

The machine as shown in Fig. 1 comprises a cast-iron frame 1 wherein arerotatably journalled two large rollers 2 and 3 adapted to rotate in thedirections indicated by the arrows. With each of these rollerscooperates a smaller roller 4 and 5 respectively also rotatablyjournalled in movable bearings (not shown) allowing the said smallerTellers to'be moved with any desired pressure against theircorresponding larger roller. The web of paper or?- other material to betreated is wound on a reel 6 and is conducted therefrom over the guiderolls 7, 8, 9, 10, 11 and under 12 to a reel 13 on which the treated orcolored paper, or other material is wound. Between the guide rolls 8 and9 is interposed a drying drum 14 around which the web of material isconducted on its way to the rollers 4 and 5.

The device for applying the treating substance, such as color, to thepaper, comprises a trough 15 of a length corresponding to diagrammaticway one 6111- the construction of a machine,

the length of the rollers 2 and 4, which trough, according to the numberof colors to be applied to the web of: paper, or other material, isdivided into a corresponding number of compartments (1, b, c, d, e, f,g, h, i, 7', etc., as shown in Fig. 2. In the trough 15, in bearingsnotshown, is rotatably journalled a roller 16 provided with projectingcircular disks of a width corresponding to the width of the saidcompartments, and arranged to dip into the color contained in the saidcompartments. In each of the said compartments is preferably provided ablock 17 of felt or any other suitable material immersed in the colorand in such a position relative to the said disks as to continuouslyapply thereto the required amount of color (see Fig. 4). The blocks 17are held by resilient arms 18 reniovably secured to the bottom of thetrough 15. From the disks on roller 16 the colors are transmitted to theweb of paper N, or other material, by means of rotatableplain rollers19, 20 and 21, rotating in the direction shown by the arrows. On theserollers, 19, 20 and 21, the colors will spread so as to mix at theirlines of contact, and in this manner, composite colors are obtained. Forinstance, if the compartments formed in the trough 15 successivelycontain red, yellow and blue, which succession of colors is continuouslyrepeated, then red and yellow in being mixed on the above saidtransmitting rollers will produce orange, yellow and blue will producegreen and blue and red will produce purple, so that the colors whenapplied to the web of paper N, or other material, will appear as red,orange, yellow, green, blue, purple, after which again comes red, etc.In this way any desired color effects can be obtained. Where, on theother hand, distinct stripes of colors shall be transmitted, then thetransmitting rollers 19, 20 and 21 instead of being plain rollers aremade like rollers 16, i. e. with disks of the same width as the disksprojecting from roller 16. Instead of the compartments of trough 15being filled with various colors, the they can, of course, be filledalso with one color only, and in that case, stripes of the same colorwill appear on the web of paper N, or other material, when the color istrans- 'mitted in the manner last described.

In Fig. 3 is shown the arrangement for filling the various compartmentsin the trough with the various colors. The case of three differentcolors e. g. red, yellow and blue, such as above described, beingassumed, then there will be provided three tanks 22, 23, 24, onecontaining the red, the next the yellow and the third the blue color.These colors flow through suitable conduits 25, 26, 27 into the firstthree compartments a, b and c. As shown in Figs. 2 and 3, compartment (1is connected through a tube 28 with compartment d, which is the firstcompartment of the next series, I) is connected through a tube 29 withcompartment 0, the second compartment of the next series, while 0 isconnected through a tube 30 to compartment 7", the third compartment ofthe next series.

In the same manner, 01, c and f are connected to compartments g, h and71 respectively, and so forth, so that the red color, for instance, willflow from compartment a into d, from (i into g from g into 9', and soforth. Yellow flows from 5 into 6, from 6 into it, and so forth, whileblue flows from 0 into f, from f into vi, and so forth. In this manner,only one color supply tank is required for each color irrespective ofthe number of compartments to be filled with the said color. The tubes28, 29, 30, etc. are arranged at the bottom of the trough 15. For eachcolor, there is also provided at the other end of the 'trough 15 anoverflow to maintain a uniform level. Into the last three compartmentsthere extend tubes 31, 32, 33 up to a height at which the level shall bekept. These tubes lead to tanks 34, 35 and 36, which are each providedwith a discharge faucet 37 38 and 39 respectively, whereas the supplytanks 22, 23, 24 are each provided with a cut-off valve 40, 41 and 42respectively.

On the end of the roller 16 projecting outside from the trough 15 thereis mounted a pulley 43 (Fig. 1) which, by means of a belt 44, is drivenby a pulley 45 on the shaft 46, rotatably journalled in bearings notshown, which shaft carries the drying drum 14. On the same shaft is alsomounted a sprocket wheel 46, driven by a sprocket chain 47 from theshaft of the roller'2, on which shaft is mounted a sprocket wheel 48.The shaft of the roller 2 is positively driven from a source of powernot shown.

In addition to the color applying device, there is shown in Fig. 1 alsoa coating device for applying melted wax, paratlin, glycerine or thelike to the bottom roller 4 when it is desired to give the paper aglazed appearance. The coating device comprises also a trough 49 adaptedto contain the coating substance. In this trough there is immersed arotatable roll 50, which takes up the coating substance and transfers itby means of two other rolls 51 and 52 to the bottom roller 4, whereby itis transmitted to the web of paper N, orother material, as it passesunder pressure between the rollers 4 and 2.

In the trough 49 is provided a steam pipe auaeaa 53 to heat the coatingsubstance where it is re uired.

esides the reels 6 and 13, there may be provided two other reels 54 and55. From reel 54 a Web of paper, or other material may be conducted overthe guide-rolls 56 and 57 between the to roller 5 and roller 3 and thenunder gui e-roll 58 to the reel 55 as shown by the dash-line N, so as tobe coated or otherwise treated, a coating device being shown at 59. Or aweb of paper, or other material may be passed from reel 54 following thepath of web N first between the rollers 5 and 3, then around 3, as shownby the dash and dot line N through the space between 3 and 2 and overthe guiderolls 60 and 7 to the guide-roll 8, then following the path ofthe web N. In this way, a web of paper or other material may be 1n oneoperation treated on both sides. I claim as my invention:
